石油设备网讯 据世界天然气网站3月21日消息 俄罗斯天然气工业股份公司（Gazprom）表示，连接土耳其溪近海和近岸部分的管道最终焊接完成，标志着整个黑海管道系统的完成。
这项技术上被称为“水上连接”的工程涉及从海床上取回近岸管道和海上管道，将它们吊至水上并焊接在一起，作业时必须提升的总重量约为409吨。
在对焊缝进行检查后，将管道降至32米深的海底。这项工程于今年1月和2月在俄罗斯水域的两条航线上进行，3月在土耳其海岸附近进行。
深水铺管以Pioneering Spirit号进行，浅水铺管作业以Lorelay号进行。
随着上述“水上连接”工程完成，俄罗斯Anapa附近的登陆设施与土耳其色雷斯Kiyikoy附近的接收终端之间实现了物理连接。
Russkaya压气站将为穿越黑海的天然气提供必要的压力，TurkStream管道系统的Anapa登陆设施也已经完成并处于待命状态。
今年晚些时候，在Kiyikoy的接收终端完工后，土耳其溪将准备投入运营，通过的天然气流量计划在2019年底开始。

Gazprom completes TurkStream offshore-nearshore sections
Russian giant Gazprom said that the final weld that connects the offshore and the nearshore sections of TurkStream was completed, marking the finalization of the entire pipeline system in the Black Sea.
The procedure, known technically as ‘Above Water Tie-In,’ involved retrieving the nearshore pipeline and offshore pipeline from the seabed, lifting them above water and welding them together. The total weight that had to be lifted for the operation was approximately 409 tons.
Following an inspection of the weld, the pipe was lowered to the seabed at a depth of 32 meters. This operation was carried out on both lines in Russian waters in January and February this year, and near the Turkish coast in March.
The pipelaying in deep waters was carried out by Pioneering Spirit, while the shallow-water pipelaying was conducted by Lorelay.
With the completion of the Above Water Tie-In procedure, a physical connection between the landfall facility near the Russian city of Anapa and the receiving terminal near Kiyikoy in Turkish Thrace is realized.
Russkaya Compressor Station, which will provide the necessary pressure for the gas to traverse through the Black Sea, and the Anapa landfall facility of the TurkStream pipeline system are already complete and on stand-by.
With the completion of the receiving terminal in Kiyikoy later this year, TurkStream will be ready to commence operations. Natural gas flow through TurkStream is planned to start by the end of 2019.
